An experimental bicycle wheel is located on a test stand so that it is free to turn on the axle. When a constant total torque of 6.00 m*N is exerted to the tire for 2.00 s, the angular speed of the tire rises from zero to 115 rev/min. The external torque is then eliminated, and the wheel is brought to rest in 125 s by friction in the bearings.
Calculate the moment of inertia of the wheel about the axis of the rotation.
Calculate the friction torque.
Calculate the net number of revolutions made by the wheel in 125 s time interval.
